Ionic liquid promoted selective oxidation of organic compounds with NaBrO3

Abstract

1-Butyl-3-methylimidazolium bromide ([bmim]Br) as an ionic liquid promoted selectively the oxidation of alkyl arenes and alcohols to the corresponding carbonyl compounds with NaBrO3 in excellent yields under neutral conditions at the 70°C. Among the various ionic liquids examined, the [bmim]Br exhibited the best performances with NaBrO3. The ionic liquid can be recycled and reused for several runs without any significant loss of activity. © 2008 Springer-Verlag.
